Great Britain made the stamp act, and the townshend act, the quartering act, ect. But it only applied to the colonies so the colonists felt that it was unfair because they had no one to represent them in Great Britain, King George wouldn't repeal any of these laws and it led to the colonists dressing up as Indians and emptying the ships of the tea into Boston Harbor (Boston Tea Party) and the Boston Massacre, and eventually led to the revolutionary war.
